FIELD OF THE DISCLOSURE

This disclosure relates generally to information handling systems, andmore particularly relates to modular datacenter server rack retention.

BACKGROUND

As the value and use of information continues to increase, individualsand businesses seek additional ways to process and store information.One option available to users is information handling systems. Aninformation handling system generally processes, compiles, stores,and/or communicates information or data for business, personal, or otherpurposes thereby allowing users to take advantage of the value of theinformation. Because technology and information handling needs andrequirements vary between different users or applications, informationhandling systems may also vary regarding what information is handled,how the information is handled, how much information is processed,stored, or communicated, and how quickly and efficiently the informationmay be processed, stored, or communicated. The variations in informationhandling systems allow for information handling systems to be general orconfigured for a specific user or specific use such as financialtransaction processing, airline reservations, enterprise data storage,or global communications. In addition, information handling systems mayinclude a variety of hardware and software components that may beconfigured to process, store, and communicate information and mayinclude one or more computer systems, data storage systems, andnetworking systems.

A modular datacenter can be a datacenter that is mobile, such that themodular datacenter can be transported to a specific location to provideadditional computing capacity. The modular datacenter can includemultiple server racks, servers, cooling devices, and other components.Additionally, the modular datacenter is typically transported with theserver racks fully loaded with information technology equipment, such asthe servers. Thus, when the modular datacenter arrives at the desiredlocation, the modular datacenter can be quickly set up and madeoperational.

The following description in combination with the Figures is provided toassist in understanding the teachings disclosed herein. The followingdiscussion will focus on specific implementations and embodiments of theteachings. This focus is provided to assist in describing the teachingsand should not be interpreted as a limitation on the scope orapplicability of the teachings. However, other teachings can certainlybe utilized in this application.

FIG. 1 shows a modular datacenter 100 of an information handling system.For purposes of this disclosure, an information handling system mayinclude any instrumentality or aggregate of instrumentalities operableto compute, classify, process, transmit, receive, retrieve, originate,switch, store, display, manifest, detect, record, reproduce, handle, orutilize any form of information, intelligence, or data for business,scientific, control, or other purposes. For example, an informationhandling system may be a personal computer, a network storage device, orany other suitable device and may vary in size, shape, performance,functionality, and price. The information handling system may includerandom access memory (RAM), one or more processing resources such as acentral processing unit (CPU) or hardware or software control logic,ROM, and/or other types of nonvolatile memory. Additional components ofthe information handling system may include one or more disk drives, oneor more network ports for communicating with external devices as well asvarious input and output (I/O) devices, such as a keyboard, a mouse, anda video display. The information handling system may also include one ormore buses operable to transmit communications between the varioushardware components.

The modular datacenter 100 includes a modular chassis 102, a server rack104, main beams 106, base beams 108, top retention members 110, andbottom retention members 112. The main beams 106 are preferablyconnected to a top panel of the modular chassis 102, and the base beams108 are preferably connected to a bottom panel of the modular chassis.The top retention members 110 are preferably connected to the main beams106, and the bottom retention members 112 are preferably connected tothe base beams 108. The server rack 104 is preferably connected to boththe top retention members 110 and to the bottom retention members 112.

The server rack 104 can be preloaded with multiple servers, shown inFIG. 3, so that the modular chassis 102 can be transported to a remotelocation for immediate use. The top retention members 110 and the bottomretention members 112 respectively can connect the server rack 104 tothe main beams 106 and to the base beams 108 of the modular chassis 102.Thus, during transportation of the modular datacenter 100, the mainbeams 106 and the base beams 108 can keep the server rack 102 fromshifting around within the modular chassis 102. The top retentionmembers 110 and the bottom retention members 112 can also isolate theserver rack 104 from vibrations within the modular datacenter 100, andcan support the server rack in the up and down, left and right, andforward and backward directions. The vibrations within the modulardatacenter 100 can be caused during the transportation of the modulardatacenter, and/or can be caused by the operation of other deviceswithin the modular chassis 102. The top retention members 110 can beadjusted on the main beams 106 to hold the server rack 104 within themodular chassis 102 under compression, tension, or neither compressionnor tension as discussed more fully with respect to FIGS. 2 and 3.

FIG. 2 shows an enlarged view of a top portion of the modular datacenter100. The top retention members 110 each have a slide member 202, anisolation mount 204, and an attachment member 206. The slide member 202is connected to the main beam 106 with bolts 208. The slide member 202,the isolation mount 204, and the attachment member 206 are held inphysical communication with each other with a bolt 210. The attachmentmembers 206 are connected to the server rack 104 by bolts 212. Theisolation mount 204 can be a center bonded isolation mount, such thatthe center of the isolation mount is metal to provide support for thebolt 210 to connect the slide member 202, the isolation mount, and theattachment member 206. The outer edges of the isolation mount 204 can bean elastomer such as rubber, such that the physical communicationbetween the attachment member 210 and the isolation mount is through therubber.

In an embodiment, the slide member 202 and the main beam 106 can berigid so that the top retention member 110 can be held within a specificlocation of the modular chassis 102. The isolation mount 204 preferablyisolates the attachment member 206 from the slide member 202 and fromthe main beam 106. Thus, the isolation mount 204 can reduce the amountof vibrations passed to the attachment member 206 from the base beam 106and from the slide member 202. The slide member 202 can be adjusted onthe main beam 106, such that the top retention member 110 can be in anuppermost position as shown in FIG. 2, a lowermost position, or anylocation between the uppermost and lowermost positions. The topretention members 110 can be placed in the uppermost position, so thatthe server rack 104 can be inserted in the modular chassis 102 betweenthe top retention members and the bottom retention members 112. Theslide member 202 can then be slid downwardly along the main beam 106until the attachment member 206 is placed at a desired location withrespect to the server rack 104. Then the attachment member 206 can beconnected to the server rack 104 with the bolt 212.

In an embodiment, the top retention member 110 can be pressed downwardwith enough force that the server rack 104 is placed in compression bythe force exerted from the attachment member 206 to the top of theserver rack. In another embodiment, the top retention member 110 can beplaced a desired height above the top of the server rack 104. Thus, asthe bolt 212 connects the server rack 104 with the attachment member206, the bolt can exert a force upward on the server rack to place theserver rack in tension. Alternatively, the top retention member 110 canbe placed in physical communication with the top of the server rack 104without exerting a substantial force on the server rack, such that thebolt 212 can connect the server rack to the top retention member withoutplacing the server rack under tension or compression. When theattachment member 206 and the top retention member 110 are in a desiredlocation along the main beam 106, the bolts 208 can be tightened to holdthe top retention member in the desired location and as a result theserver rack 104 can be held in either compression, tension, or neithercompression nor tension.

The compression and/or tension of the server rack 104 can change thenatural frequency of the server rack, which can provide additionalprotection to the servers within the server rack from vibrations causedby other devices within the modular datacenter 100, and/or thetransportation of the modular datacenter. The change in the naturalfrequency of the server rack 104 can cause the natural frequency of theserver rack to be different than the frequency of the vibrations. Thus,the change in the natural frequency of the server rack 104 can preventthe vibrations within the modular chassis 102 from resonating within theserver rack 104. In an embodiment, the top retention members 110 can berotated ninety degrees, such that the top retention members align withand operate similar to the bottom retention members 112 as discussedbelow with respect to FIG. 3.

FIG. 3 shows an enlarged view of a bottom portion of the modulardatacenter 100 with a plurality of servers 302 placed within the serverrack 104. The bottom retention members 112 each have an isolation mount304, an attachment member 306, a spacer 310, and a compression member310. The isolation mount 304, the attachment member 306, and the spacer310 are connected to the base beam 108 with a bolt 312. The bottom ofthe server rack 104 is in physical communication with the compressionmember 310, and connected to the attachment member 306 with a boltand/or a screw.

When the server rack 104 is placed within the modular chassis 102, theserver rack can be placed on the compression members 310 of the bottomretention members 112. The weight of the server rack 104 and the servers302 is preferably supported by the bottom retention members 112, and thecompression members 310 preferably provide a first isolation barrierbetween the bottom of the server rack and vibrations from the modularchassis 102. The attachment member 306 is preferably composed of a rigidmaterial capable of supporting the weight of the server rack 104 and theservers 302.

The isolation mount 304 is preferably a center bonded isolation mountsimilar to the isolation mount 204 discuss above. Thus, the isolationmount 304 can provide isolation between the attachment member 106 andvibrations within the base beam 108. If the top retention member 110 isplaced in a position along the main beam 106 such that the server rack104 is placed in tension, the server rack can be lifted slightly and thecompression of the compression members 310 can be decreased. In thissituation, the bottom retention members 112 do not have to support theentire weight of the server rack 104.

FIG. 4 shows a flow diagram of a method 400 for installing a server rackinto a modular chassis of a modular datacenter. At block 402, a topretention member is placed in an uppermost position on a main beam ofthe modular chassis. The server rack is placed on a bottom retentionmember of the modular chassis at block 404. The server rack ispreferably placed on a compression member of the bottom retentionmember. At block 406, the server rack is fastened to an attachmentmember of the bottom retention member. The attachment member ispreferably isolated from a base beam of the modular chassis via anisolation mount. The isolation mount can reduce or prevent vibrationswithin the modular chassis from being transmitted to the server rack andthe servers. The vibrations can be caused by the transportation of themodular datacenter and/or caused by the operation of other deviceswithin the modular chassis.

At block 408, a determination is made whether the server rack is to beplaced in compression. If the server rack is to be placed incompression, the top retention member is pressed downward until theattachment member of the top retention member exerts a force on theserver rack to cause compression of the server rack at block 410. Theattachment member of the top retention member and the server rack arepreferably isolated from vibrations within a main beam of the modularchassis via an isolation mount. The server rack is connected to theattachment member at block 412. If the server rack is not to be placedin compression, a determination is made whether the server rack is to beplaced is tension at block 414.

At block 416, if the server rack is to be placed in tension theattachment member is placed at a desired height above the server rack,the server rack is connected to the attachment member, and the serverrack is held in tension. The server rack is connected to the attachmentmember at block 412. If the server rack is not to be placed in tension,the attachment member is placed in physical communication with theserver rack without exerting enough force on the server rack to placethe server rack in compression at block 418. The server rack isconnected to the attachment member at block 412.
